Additive Noise Channel

This function is the matlab implementation of Additive Noise Channel

Additive Noise Channel / Additive Guassian Noise Channel is the simplest of all channels. File usage details:

op_channel = additivenoise(input_signal)

mathematical Model:
s(t) input signal to channel (=sig_ip)
n(t)additive random noise process added by channel (=noise_mat)
a(t) attenutation factor , here it is taken as random(=att_fact)
out put signal r(t) = a .* s(t) + n(t)

an additional file named through_anc is there which shows 2 figures, 1. input signal 2. output signal
